Food or sex: which would you choose? Pollinator-prey conflict and reproductive assurance in New Zealand Drosera
(Lincoln University, 2009)
This is the first study to test the possibility that autonomous selfing in carnivorous plants functions as a mechanism to reduce the pollinator-prey conflict by reducing pollen-limitation. Carnivorous plants can rely on ...
Molecular systematics and colour variation of Carpophilus species (Coleoptera: Nitidulidae) of the South Pacific
(Lincoln University, 2009)
The sap beetle genus Carpophilus Stephens (Coleoptera: Nitidulidae) is a large genus consisting of over 200 species and are found worldwide. Several species are important pests of crops and stored products, and are frequently ...
Biochemistry and genetics of carotenoid composition in potato tubers
(Lincoln University, 2009)
Potato cultivars exhibit a wide variation in skin and flesh colour due to the presence of pigments. This study established that potato cultivars differ greatly with respect to types and concentrations of carotenoids in ...
Objective functions for comparing simulations with insect trap catch data
(Modelling and Simulation Society of Australia and New Zealand and International Association for Mathematics and Computers in Simulation, 2009-07)
Targeted surveillance of high risk invasion sites using insect traps is becoming an important tool in border biosecurity, aiding in early detection and subsequent monitoring of eradication attempts. The mark-release-recapture ...
Residual concentrations and persistence of the anticoagulant rodenticides brodifacoum and diphacinone in fauna
(Lincoln University, 2009)
Brodifacoum is a highly effective anticoagulant rodenticide that presents a secondary hazard to some non-target wildlife. The high acute toxicity of brodifacoum to mammals and birds, and its prolonged persistence in liver ...
Development of a tomato/root knot nematode bioassay to screen beneficial microbes
(New Zealand Plant Protection Society (Inc.), 2009)
In common with other root knot nematodes Meloidogyne hapla is a serious plant pest. A rapid screening system for candidate microbes that benefit plant growth is a first step to developing screening bioassays in ...
Modelling the proximal source of intercepted exotic insects
(Lincoln University, 2009)
Biological invasions are major threats to any nation’s economy and biodiversity. To detect new biological incursions of some species biosecurity agencies deploy pheromone sentinel traps for targeted species at high risk ...
Influence of root exudates on soil microbial diversity and activity
(Lincoln University, 2009)
Interactions between plant roots and soil microorganisms in the rhizosphere are critical for plant growth. However, understanding of precisely how root exudates influence the diversity and activity of rhizosphere microorganisms ...
Influence of natural enemies on Cirsium arvense — a biogeographic perspective
(Lincoln University, 2009)
Cirsium arvense (L.) Scop. (Californian, Canada, or creeping thistle) is an exotic perennial herb indigenous to Eurasia that successfully established in New Zealand (NZ) approximately 130 years ago. Presently, C. arvense ...
Distribution and spread of environmental weeds along New Zealand roadsides
(New Zealand Ecological Society., 2009)
Most non-native weeds and other naturalised plants are in the early stages of invasion into New Zealand landscapes. For this invasion to be controlled, even partially, it is important to understand the dominant routes, ...
